Every day, especially in the morning, Coco has some gunk on her eyes. Its not around her eyes, but you can actually see clear mucous on her eye. It moves around and doesn't seem to bother her, but it bothers me because I can see it! So I blink her eyes and rub the a bit until I can pull it out. It is clear, doesn't smell or anything, but is pretty thick. I got some dog eye wash to help flush it out which I also use once in a while.
